Find the first two orthogonormal polynomials on [-1,1]

1. What is orthogonormal? [2]

2. What is orthogonal? [3]

3. What is a polynomial? [4]

        a
        bt+c

4. Now we can find the values for the unknown variables.

<a|a>=11aadt=1
a=12


<bt+c|a>=11a(bt+c)dt=0
c=0
<bt+c|bt+c>=11(bt+c)2dt=1
b=(32)


5. Now that we know what the first two orthogonormal polynomials!
